savvi 0 Report post Posted June 1, 2009 hi guys my e30 325 is having real problems keeping idle have had the intake manifold off to get the injectors serviced now that is back together the car is very poor idle only just ticks over, and when i accelarate and change gears or at idle and or give it gas the revs are very slow to return this must be an air leak but ive come up with nothing the coolant tube from the bottom of the thermastat to the throttle body and the one from the block to the throttle body if they were back to front would that cause the problem i have cheers for any help shane Quote Share this post Link to post Share on other sites
Guest FrantiC Report post Posted June 1, 2009 You shouldn't have to remove intake manifold to get the fuel rail out. But yeah you definitley have a vacuum leak somewhere. Did you put new injector o-rings when you put them back in?? New intake manifold gaskets? no cracks in the intake boot? No, those coolant lines don't effect it.

Can be done with it in. Get yourself new gaskets and o-rings. The gaskets can only be used once - Once compressed they won't seal properlly again.

Guest FrantiC Report post Posted June 10, 2009 What about your spark plug leads are they pushed onto the spark plugs properlly ? Hows your dizzy cap looking ? I still vote vacuum leak, but running on 5 cylinders is odd. Injector leads aren't able to be mucked up they are all set out with no slack between so you can't really have them plugged in the wrong way. Quote Share this post Link to post Share on other sites
